SPECIFICATION forming part of Letters Patent No. 762,456, dated June 14,1904.

To rtZZ whom it may concern:

Be it known that I, J our W. TODD, a citizen of the United States,residing at Dunkirk, in

' the county of Jay and State of Indiana, have invented certain new anduseful Improvements in renches; and I do declare the following to beafull, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to new and useful improvements in wrenches, andcomprises a sliding-jaw wrench having a spring-actuated means forholding the jaw in an adjusted position; and the object of the inventionis to produce a wrench which may be easily and quickly adjusted withoutnecessitating the turning of a screw and securely held in an adjustedposition.

The invention consists, further, in various details of construction andin combinations and arrangements of parts, which will be hereinafterfully described and then specifically defined in the appended claim] Myinvention is illustrated in the accompanying drawings, which, with theletters of reference marked thereon, form a part of this application,and in which drawings similar letters of reference indicate like partsin the several views, in which- Figure 1 is a perspective view of myimproved wrench. Fig. 2 is an enlarged perspective detail view of asliding jaw, showing the spring depressed to allow the jaw to be movedupon the shank portion of the fixed jaw. Fig. 3 is a perspective view ofthe removable jaw, showing the same in a locked relation to hold the jawin its adjusted position.

Reference now being had to the details of the drawings by letter, Adesignates a fixed jaw having a shank portion B with handle U thereon ofthe usual construction, and D designates a movable jaw which ischambered out to receive the shank portion B, upon which said jaw moves,and has also a threaded bore E, adapted to receive the screw F, having amilled head F, whereby the screw may be turned in one direction or theother. Said screw is suitably journaled upon the shank portion of thefixed jaw with the head turning in a recessed portion of said shank. Aportion E of the wall of the threaded bore of the movable jaw is madeseparate from the movable jaw, as shown clearly in Figs. 2 and 3 of thedrawings, and a stirrup K is fastened to the separate section E and thespring H is fastened at one end to the movable jaw A of the wrench,while its other end is adapted to bear against one end of said stirrup,as shown in the drawings, and the object of the spring is to normallyhold the movable section E, as illustrated in Fig. 3 of the drawings, orin position to form a closed bore with registering threads for thereception of the screw F. 7

The operation of the wrench is as follows: I/Vhen it is desired to movethe jaw D upon the shank portion B, the operator merely pushes in uponthe spring-engaging end of the stirrup, which will cause the part E tobe raised from the movable jaw, as shown in Fig. 2, after which the jawmay be moved freely upon the shank portion B without interference fromthe threads of the screw F, and when the jaw is in an adjusted positionby releasing pressure from the spring-actuated stirrup the part IE willclose, as shown in Fig. 3, and the threads on said part will engage thethreads of the screw to hold the sliding jaw in its adjusted position.If desired, however, the wrench may be used as an ordinary movable-jawwrench actuated by means of the screw, although time may be saved byutilizing the spring-actuated stirrup.

While I have shown a particular construction of apparatus embodying thefeatures of my invention, it will be understood that I may vary thesame, if desired, as to details of construction without in any waydeparting from the spirit of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In combination with a fixed jaw with shank portion, a sliding jaw havinga chambered sliding jaw mounted upon said shank portion,

a screw carried by the shank portion of the against fixed jaw andengaging the threaded wall 01 an aperture in the movable jaw, one of thewalls of the threaded aperture being fixed 5 and the other movable andadapted toseat' upon a shoulder formed in the edge of the sliding jaw,and an integral stirrup-shaped member integral with said movable walland surrounding one end of the sliding jaw, and 10 a spring secured tothe latter and bearing said stirrup member designed to normally hold themovable wall against said shoulder, as shown and described.

In testimony whereof I hereunto aflix my signature in presence of twowitnesses.

JOHN W. TODD.
